Chapter 5 WAN Setup The following table describes the labels in this screen. Table 20 Network > WAN > Multicast LABEL DESCRIPTION WAN Interface Select the WAN interface you want to use for multicast traffic. Refer to Section 5.2 on page 76 to know more about WAN interfaces and read about Multicast on page 91. Traffic received on this interface is sorted according to multicast membership. WAN Status Apply Cancel Select Disable Multicast if you do not want to use any WAN interface for multicast traffic. This shows whether the WAN interface is currently Up (available) or Down (not available). Click this to save your changes back to the ZyXEL Device. Click this to begin configuring this screen afresh. 5.5 Technical Reference The following section contains additional technical information about the ZyXEL Device features described in this chapter. Encapsulation Be sure to use the encapsulation method required by your ISP. The ZyXEL Device can work in bridge mode or routing mode. When the ZyXEL Device is in routing mode, it supports the following methods. IP over Ethernet IP over Ethernet (IPoE) is an alternative to PPPoE. IP packets are being delivered across an Ethernet network, without using PPP encapsulation. They are routed between the Ethernet interface and the WAN interface and then formatted so that they can be understood in a bridged environment. For instance, it encapsulates routed Ethernet frames into bridged Ethernet cells. PPP over Ethernet Point-to-Point Protocol over Ethernet (PPPoE) provides access control and billing functionality in a manner similar to dial-up services using PPP. PPPoE is an IETF standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.) connection. For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for example RADIUS). FSG2200HNU User's Guide 89
